Question 974250: graph the equation to solve the system problem one y=1/3x+1 and y=-1/2x-4.
problem two y=-1/2x and y=-1/3x+1.
problem three y=1/3x +2 and y=-1/3x-2.
Please show me the graph and how you got the answer.
Are they no solution, one solution, all numbers on the line, I don't understand how to solve the problem in order to graph it.
Please help if you can. Marisa

Graph the equation to solve the system::
problem one y=1/3x+1 and y=-1/2x-4.
Substitute and solve for "x"
(1/3)x+1 = (-1/2)x-4
[(1/3)+(1/2)]x = -5
(5/6)x = -5
x = -6
---
Solve for "y"
y = (1/3)x+1
y = (1/3)*-6 + 1
y = -1

------------------
problem two y=-1/2x and y=-1/3x+1.
Solve for "x":
(-1/2)x = (-1/3)x+1
-------
[(1/3)-(1/2)]x = 1
-1/6 x = 1
x = -6
---
Solve for "y"
y = (-1/2)x
y = 3
